It isn't up and running yet. Keep watching the series, I will get it done eventually. I've been running conduit this weekend and ran out of some materials for the job.

They get to do that as they own the servers and host the videos, I don't get a dime from it. It takes something like 4K subscribers and over 10K views in 30 days to get paid something. Many channels pay bot farms to get the count up. I don't need to get paid anything, this is for sharing my experience and documentation. I find myself going back to my own videos to remember how I did something.

@doczwy8143 I'm not accusing u of getting paid I know neither of us can get monetized just funny how they can do whatever they want

Plates are 3/8" thick. Poron I'm using is 3.17 mm thick, I think it was written on the table when I was doing the math. Compression of Poron at 25% on the 17 sheets would be 13.47 mm total. If you have rods in the middle, it shouldn't flex. It is possible you might have too much compression.

@doczwy8143 ya I have a rod in the middle. The whole plate isn't flexing just a tiny tiny bit at the 4 corners

You must have missed the Tornado Damaged Solar Mount video.🤣

Yes, 74Kwh in house and shop system will be separate with 114Kwh plus I have another 14Kwh Luyuan box in my work trailer I can roll into the shop over the winter. Over 200Kwh total. In a future video, I will cover power transfer from one system to the other.

@@doczwy8143 Nice, I use to live in north central Iowa. I worked on the wind turbines there.

@@OGBRADASS Plenty of turbines here, 66 added just last year with more on the way. We already had about 4 wind farms here with average size of about 30 to 40 turbines.

I will be pulling 16 cells from my house bank that have had foam since installed 2 years ago. I can video it and show any cell expansion. I've never seen any expansion when top balancing the old way and those are done in compression with foam as shown in the video. I tear every pack down in order to move it.

@@doczwy8143 Could be that people charged them before they compressed them, and why the foam was compressed 50% more in the center when they took them apart.

@@doczwy8143 Can you go through all your Batrium settings on video? And explain what some of the settings mean. There is A LOT of options.

@@OGBRADASS There certainly are many options. It would be some time before I could get a video done as I'm currently pushing to get my shop system done. I'll see what I can put together.

@@doczwy8143 Thanks! I just got up and running!

I'll check it out, I'm a member there but rarely go there.

@@doczwy8143 Thanks! I think I will go with K9 eventually. For now I'm kinda stuck with what I got budget wise. Once I have money to get more batteries I'll order k9s aswell.

Any tariffs for cells should be in 2026 but that could change. I need another 48 cells to finish out the next build and should order those soon.

@doczwy8143 great! I was looking to buy those cells recently and most gets delivered after the end this year. some even around February. now I know I got time just in case I need to RMA. Appreciate the info, doc!

@@jeffw7889 Just remember the Chinese New Year starts on Jan 29th,2025. You won't get anything shipped out until Feb 3rd. If you have cells ordered already, you should be fine.

My assumption is the actual solder joint is on the backside, the male spade goes thru the pcb.

Could be, it certainly has been a test of not only the equipment but my patience. The charge controller itself works fine, I've run over 15 Mwh thru these charge controllers. The failures were at the connectors and I have bypassed the connector and recommend anyone with this unit to also bypass the connector.

Sometimes a dual breaker like this is looped to increase the voltage rating to double. This breaker is rated for 500V and that is what the charge controller is rated for so no reason the series connect the positive thru the breaker. This was discussed on the DIY Solar Forum. As for the flattened ferrule, the original ferrules in the failed charge controllers had deep ridges and reduced the contact area by 1/2. I think this might be a major contributor to the connectors failing.

I would replace the pair with something like the SRNE ASP 10KW if I needed something bigger or these fail. The LV6548's run everything we need to run in the house. I would add more battery and more PV for expanding the house system. We heat mainly with heat pumps until Dec/Jan and hot water is mainly with heat pump water heater. Possibly next year we will move to a heat pump dryer.

Thanks Joe, I'm building another for my shop. Bigger box and bigger inverters.

Andy's Garage has some videos about using the Peter Board (board is more than a BMS) or ESP device with Home Assistant (basically free) and this was using the older JK BMS's. I don't use inverter communication, I like to keep things simple and set my charging voltages. Communication adds complexity and a failure point. I would definitely buy more cells and more boxes. I'm probably building another box or two for other projects. As for 280Ah vs 304Ah cells, it's just a matter of price and preference.

@@doczwy8143 Hello Doc, can provide the links where you got the cells and the BMS?

@@lowfat1713 I'll put it in the description as links in comments TH-cam tends to delete.

It is for primarily for maintaining cell cycle lifespan. Cell manufacturers have a specification for cell compression to achieve cycle lifespan. This specification is listed in the manufacturer spec sheet. It also does prevent excessive expansion which could lead to side loading on battery terminals when using solid busbars, Terminal failure could lead to cell failure and possible cell ignition. The Luyuan box has minimal compression as shown in that video. I added Poron on each end as cells were loose in the case and there wasn't any compression. The latest cells are now shipped with flexible busbars and I show that construction in the Luyuan box video. Long term use will determine whether calendar aging has a bigger effect on cell lifespan than not having any compression.

I decided to use various inverters and charge controllers as part of testing these products for real life long term usage and relate that experience to others. Victron has some good products and I own some of them. The shop system currently being built almost had Victron 10Kw Quattros installed but I decided to try SRNE ASP 10Kw units. As technology keeps increasing in the PV system arena there will be more features and advanced inverter tech coming online. 5 years from now I might be using something different. Battery tech might change and that may have a huge influence on what inverters are available.

@doczwy8143 ok. Nu știu dar SRNE este de frecvență joasă? Oricum ai făcut o treabă grozavă👍

@@invertor4245 SRNE is HF. If you like this video, you will like the video covering the shop system.

Thank you. Come join the DIY Solar Forum if you are interested in solar and want to learn.

That is a good question. We have actually increased electrical usage since the system was turned on. We now heat the house using heat pumps when there is excess PV coming in, hot water is now heated by a heat pump water heater. The utility company increased electric rates for the next 5 years by 15% and will be increasing fees. I was shooting for 10 years and that might be about right. I did spend extra on the MT Solar mount and the BMS using the Batrium. I originally was looking for backup power using a standby generator and saved that cost. I'm currently building a system for the shop which the total cost will be depreciated out over 7 years. I also learned how to cut some costs and that payback will probably be about 5 years. I found some used tornado damaged mounts which saved about $6K alone. A deal on a pallet of 31 370W panels for $2K. SRNE ASP inverters for less than $2K. All of this is an ongoing project to become energy independent as much as possible. We are living more comfortably. In my coming years if I retire I will have energy security. I had the money for the system and I am receiving a return higher than what I would receive for interest in the money market. It's not for everyone but for us this was the right decision.

Have you updated the firmware? I did a video on the process so check that out. You will need the special cable from EG4. They sent mine free of charge. I haven't upgraded the firmware on my latest replacement charge controller and it occasionally acts the same as yours in low light condition and will set the code. I need to get that job done along with updating the Batrium firmware. Firmware update is available on the EG4 website, just Google EG4 firmware and the Downloads link will be one of the first links on the search. I'd link it but TH-cam doesn't allow links in comments.

Just shy of 15 Mwh as of today. With the 58 Kwh we could run 5 days with no PV yield if we managed loads such as no laundry or dishwasher. With 72 Kwh we hope to go 6 days. I do use heat pumps for heating and have a heat pump water heater with a gas in series after it and we shut those off for forecasted poor PV yield. I'm currently building my shop system and that cabinet could hold 114 Kwh plus have another Luyuan 14 Kwh box like the one shown in the video.

I think Doc and I have been running ours close to the same amount of time. I just looked at mine and they have had 14mw ran through each of them. Since they're 120v each I'm guessing that would be considered 14mw total. I don't see how Doc gets that many days out of his batteries, but then I have a fairly heavy load on ours and not enough PV production. I'll be remedying the latter soon.

@@doczwy8143 I'm going to have to hustle and catch up with you on batteries if you're doing all that. I'm up to 90 kWh right now. This time of year that would run us a couple of days if I had no production and was careful. I see more DIY batteries in my future.

@easttexascowboy257 You all have a lot of storage capacity. How much energy does a heat pump water heater use? In 2026 once California starts the $26 connection fee I'll look into my options on my nat gas instant water heater if they don't let me keep the gas connection without the electricity.

@@Gary-ee3kq As with most things, that will vary a lot depending on usage. It's definitely way better than a standard water heater with resistive elements. I have two NG on demand water heaters and our cook top is gas also. If you can go gas that's the best option. We heat and cool around 4k sq ft and have 5 freezers, two fridges, and the usual lights and outlets etc. I don't have the dryer or electric oven on solar but that may be coming some day. The Mitsubishi heat pumps save me on the HVAC costs but it's still a heavy load in summer and the few cold spells we get.

No, this is an off grid system without any grid interconnection. Systems like yours will feed battery power to grid but one must remember it also takes away from your battery reserve power. Many are using a grid tie interconnection with the array coupled with hybrid inverters. This allows for storing some power on the grid, some in batteries and allow for excess to be put on the grid once batteries are full and loads fully met. Those can feed battery power to grid, it would depend on the agreement. Much of this depends on location and whether the utility offers enough incentives for it to work for the solar property owner. I prefer to keep things simple and not have to play by utility company rules. I've seen cases where there was a contract for $X.XX/kwh paid for grid tie excess only to see the utility change the agreement to get out of paying. 1 to 1 net metering and grid tie are probably heading towards extinction IMO simply because the utilities don't need the average homeowner generator when PV systems are getting cheaper everyday.

@@doczwy8143 I agree the gov and utilities always bait and switch to get their agenda's passed then stiff you even if its in writing.... been there done that never again.. off grid and let them play their games with their captive markets..I will not finance their schemes anymore..

No, I don't have the need. The camper is separate from the truck.

Amy Wan- Shenzhen Luyuan Technology Co., Ltd. on Alibaba. She can custom build for you. I'll add a link in the video description.

What size and how many panels in the strings? That would be the first place I'd start. The MPPT operating range is 450V. If between 450V and 500V the MPPT will not charge. Over 500V and it might fry the MPPT. Other than that I'd contact support for a replacement. 3 year warranty.

I purchased the lines from Supply House. The lines are made by RectorSeal. I flared the ends so the lines could be replaced easily. These can be brazed.

I usually leave the screen protector on until it gets scratched enough. Maybe get a few more years out of something. I am frugal, as stated in other videos, I don't throw things away if I might have a use for it. 😁

Nooooo! If you do that it's not new anymore.

@@doczwy8143 yes, protect the screen from scratches for as long as you can.
